Michael Myers

Menace
Michael Myers enters the battlefield with a mask counter on it. As long as he has a mask counter he
has hexproof.
At the beginning of your end step, if a creature died this turn put a +1/+1 on him.
When Michael Myers dies, if he has a mask counter on him, return him to the battlefield with a +1/+1 counter and no mask counter.
